Hi everyone had a problem with my C5 2.2 hdi which started a few months ago ,many thanks to those who reply to my past topics anyway getting back to it had a rough engine on startup from cold and at last I am please to say I think I have found the problem INJECTOR CONES .I found a diesel specialist who luck would have it also had a C5 but a 2.0 hdi he told me he had the same problem when starting his car from cold it would rock back and forth until warm .Once warm you would never guess there was a problem.
So for all you C5 owners out there if you have the same problem find a diesel specialist and tell him you think it could be your injectors
